# Multi-age 3–6, mathematics, Year A – Unit 07

This 2-week unit develops the big idea that multiplicative thinking involves flexible use of multiplication and division concepts, strategies and representations.

## Syllabus

Outcomes and content descriptors from Mathematics K–10 Syllabus (2022) © NSW Education Standards Authority (NESA) for and on behalf of the Crown in right of the State of New South Wales, 2024.

Students are provided opportunities to:

- generate and describe patterns (Stage 2)
- use arrays to establish multiplication facts from multiples of 2 and 4, 5 and 10 (Stage 2)
- determine products and factors (Stage 3)
- use partitioning and place value to multiply 2-, 3- and 4-digit numbers by one-digit numbers (Stage 3)
- represent and solve division problems.
